Building an app is great fun as a developer, until the design refuses to cooperate...

Everyone who builds with Mendix knows the moment. The logic works, the data is right, and then the real work begins: the app has to look good and feel right. Hours go into a button that needs to be just a little different, a data grid that doesn't match the brand, a form that looks cluttered.

Atlas gives you a solid base, but it stops at the core components. After that, you're on your own. That's why we built Catalyst: a design system that sits on top of Atlas and gives your app a modern, consistent interface from day one.

Today, Catalyst 2.0 is live on the Mendix Marketplace!

What's in Catalyst 2.0

  • One token structure for color, radius, spacing and fonts.
  • Your brand in one file, including your logo for light and dark mode.
  • New widgets: Custom button, Custom choice, Avatar and Custom badge.
  • A fresh update for alerts, group boxes, combo boxes, sliders, tree view, badges, chat and Data Grid 2.
  • A lighter theme: more than 2.5 MB less CSS.

Catalyst 2.0 works with Mendix 11 (Studio Pro 11.12.4 or higher) and Atlas Core 4.4 or higher.
